TOOTH REDUCER Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: invention relates to machine engineering, in particular to the machine parts, and can be used in the tooth weel gears placed in the closed casings - tooth gear reducers with crankcase lubrication by immersion. A tooth gear reducer contains a closed casing with stiffeners located therein and an oil bath with a liquid lubricant, where the downstream tooth weel of the tooth weel gear is immersed. There are through windows in the stiffeners adjacent to the casing walls. The bottom of the windows is located at the upper level of the casing bottom. The top of the windows is located above the upper level of the oil bath. The stiffeners are made widened inside the tooth gear reducer casing.

EFFECT: improving lubrication quality is achieved.
